The frequent use of frying oil stimulates the spread of cancer

WASHINGTON (Reuters) – According to a recent US study, vehicles containing cooking oils that are repeatedly reused at high temperatures can cause the proliferation and spread of breast tumors and move them to other parts of the body. body.
The study, conducted by researchers from the University of Illinois, published the results of the latest issue of the scientific journal "Nutrition Research".
To achieve the results of the study, the team studied a group of mice, divided into two groups, the first dealing with unheated soybean oil, while the other group consumed fried foods in soy oil, which was reused for 16 weeks.
The team explained that it chose soybean oil because it is widely used by food companies for high-temperature frying.
To simulate and monitor the spread of cancer cells, the team injected 4T1 mice into the mice, an aggressive form of breast cancer that can be automatically transmitted to multiple sites in the body, including the lungs, liver, and lymph nodes. lymphatics.
After 20 days of injecting cancer cells into mice, the primary tumors involved mice that consumed repeatedly reused oils at temperatures greater than 4 times their growth and spread, compared to mice that consumed mice. Fresh soybean oil, where tumors passed from breast to lung.
